With the Taliban gaining influence in Afghanistan and Pakistan Gordon Brown has visited the region to push a new security strategy.The British prime minister arrived in his country’s main military base in Helmand province — a key battleground with Taliban in Afghanistan — before travelling on to meet President Hamid Karzai. The new strategy is expected to be unveiled on Wednesday. British officials say it will reflect a US plan to fight al Qaeda and Taliban militants on both sides of the border. It will also stress the need to train tens of thousands more Afghan soldiers and police to take over responsibility for security from foreign troops. There will also be new development funds for the two countries’ northern border region.
